Overview

EN 2209:2008 is a European standard developed by CEN that defines the specifications for Steel FE-PL1502 (25CrMo4), a high-strength alloy tailored for aerospace applications. This standard covers steel sheets, strips, and plates with thicknesses ranging from 0.5 mm to 20 mm and tensile strength between 900 MPa and 1,100 MPa. Specifically designed for the aerospace industry, it ensures materials meet rigorous mechanical and chemical property requirements to support structural integrity, safety, and performance.

Key Topics

  • Material Specification
    EN 2209 covers steel designated FE-PL1502 (25CrMo4), specifying chemical composition limits that include carbon (C), silicon (Si), manganese (Mn), chromium (Cr), molybdenum (Mo), and other alloying elements essential for strength and durability.

  • Mechanical Properties

    • Tensile strength (Rm): 900 MPa ≤ Rm ≤ 1,100 MPa
    • Proof stress (Rp0.2): minimum values depending on thickness
    • Elongation and hardness requirements to assure ductility and wear resistance
    • Impact strength values ensure toughness at ambient temperature for thicknesses ≥ 10 mm
  • Forms and Dimensions
    Material is supplied in forms including sheets, strips, and plates with thicknesses from 0.5 mm up to 20 mm, suitable for a variety of aerospace structural components.

  • Heat Treatment and Delivery Conditions

    • Annealed, normalized and tempered, or hardened and tempered conditions
    • Typical heat treatment includes quenching at 850–880 °C followed by tempering at or above 520 °C
    • Delivery condition codes (A, B, U) correspond to specific heat treatment states
  • Testing and Inspection

    • Mechanical testing references per EN 4700-1
    • Dimensional and marking inspections ensure compliance with aerospace quality standards
    • Qualification procedures align with EN 9133 to standardize aerospace part reliability

Applications

EN 2209:2008 steel is primarily utilized in the aerospace industry where high strength-to-weight ratios and material reliability are crucial. Practical applications include:

  • Aircraft structural components such as frames, reinforcements, and brackets
  • Engine parts exposed to high mechanical stresses
  • Landing gear and support assemblies requiring toughness and fatigue resistance
  • Aerospace manufacturing requiring weldable, high-performance steel sheets and plates

This steel grade offers a balance between mechanical strength and processability, making it ideal for critical aerospace parts that demand consistent performance under extreme conditions.

Related Standards

EN 2209:2008 is part of a comprehensive framework of aerospace metallic material standards, including:

  • EN 4258: General organization and standardization principles for aerospace metallic materials
  • EN 4500-5: Rules for drafting and presenting aerospace material standards, specifically steels
  • EN 4700-1: Technical specification for steel and heat-resisting alloys in wrought form (plates, sheets, strips)
  • EN 9133: Quality management and qualification procedures for aerospace standard parts

Following these interconnected standards ensures cohesive quality, uniformity, and regulatory compliance in aerospace material selection and use.
